COMPRESSION PLATENS
For Universal, Dynamic, and Fatigue Testing Machines
Compression platens are used to perform compression tests on a wide range of materials and components. When installed in a Universal Testing Machine they allow a variety of tests to be performed to determine compression modulus, compression strength, and compression yield strength.

50 N - 600 kN Load Capacities
Principle of Operation
Easy to install, the 2501 Series compression platens are precisely machined fixtures that are designed for even distribution of compression loads during a test. These platens have a hardened surface (Rockwell HRC 58/60) for compression tests in which uniform stress distribution is critical.
Application Range
Type of loading: Static compression, compression-compression cyclic tests
Specimen material: Foam, plastic, metals, alloys, packaging, wood, composites, ceramics and other materials
Specimen shapes: Square, cylindrical cubes, components
Key Features
Sizes and Load Capacities
While the 50 mm and 150 mm diameter platens are most common, the 2501 Series is offered in a range of sizes between 25 mm – 300 mm with load capacities between 50 N – 600 kN.
Concentric Rings
To aid the operator on the larger diameter anvils, the 150 mm to 300 mm diameter platens are laser etched with concentric rings to allow for easier centering of the specimen body.
LVDT Mounting
The edge of the platen has a provision for the attachment of optional displacement transducers, allowing you to measure the direct displacement between two equal sized platens during a test.
Lock Nut Design
Designed for easy hand-tightening to eliminate backlash.
Self-Aligning | High Force | Fatigue Rated
Self-Aligning / Spherical Seatings
For Static and Dynamic Testing Applications
During the application of a small preload, the spherical seated compression platen provides the self-alignment required to accommodate compression specimens which have surfaces that are not completely parallel.
